Van Damme L, Ramjee G, Alary M, et al. Lancet. 2002; 360:962–964 Purpose of the Study. Nonoxynol-9, marketed as a spermicidal contraceptive, has in vitro anti-human immunodeficiency virus (HIV) activity. This study was designed to assess the effectiveness of COL-1492, a nonoxynol-9 vaginal gel, in the prevention of HIV infection in women with a high risk of HIV exposure. Methods. This was a ran...

BACKGROUND & OBJECTIVES Though nonoxynol-9 (N-9) is available in India as a spermicidal pessary, data on its safety as a potential microbicide among Indian women are not available. Nonoxynol-9 containing compounds have shown anti-HIV activity in in vitro studies and protection against cervical infections. Nonoxynol-9 is being extensively evaluated as a vaginal microbicide world-wide. We assesse...

BACKGROUND Nonoxynol-9 (rINN, nonoxinol-9) is an over-the-counter spermicide that has in-vitro anti-HIV-1 activity. Results of studies of its effectiveness in prevention of HIV-1 infection in women have been inconclusive. We aimed to assess effectiveness of this vaginal gel. METHODS We did a randomised, placebo-controlled, triple-blinded, phase 2/3 trial with COL-1492, a nonoxynol-9 vaginal g...

This study investigates the crystallization of the endogenous surfactant nonoxynol 100 in Eudragit NE30D-free films during storage and the influences of nonoxynol 100 on the dissolution of diphenhydramine hydrochloric acid (HCl) pellets coated with Eudragit NE30D before and after aging at ambient conditions. Polarizing light microscopy showed that when Eudragit NE30D-free films were stored at a...

BACKGROUND AND OBJECTIVES There are conflicting opinions on whether to recommend spermicides containing nonoxynol-9 for prevention of sexually transmitted diseases, including human immunodeficiency virus (HIV). GOAL To systematically review and summarize the medical literature on the effect of spermicides containing nonoxynol-9 on prevention of gonorrhea, chlamydial infection, and HIV. STUD...

A critical gap in microbicide development is the absence of surrogate safety markers. The objective of the present study was to develop a murine model to examine the mucosal response to microbicides and to assess the functional implication of observed changes. Mice received 14 daily intravaginal doses of nonoxynol-9, PRO 2000, or placebo gel. Nonoxynol-9 induced an inflammatory response charact...

Tenofovir gel is being evaluated for vaginal and rectal pre-exposure prophylaxis against HIV transmission. Because this is a new prevention strategy, we broadly assessed its effects on the mucosa. In MTN-007, a phase-1, randomized, double-blinded rectal microbicide trial, we used systems genomics/proteomics to determine the effect of tenofovir 1% gel, nonoxynol-9 2% gel, placebo gel or no treat...
